CPV


Pumps of type family CPV are constructed as single stage vertical double inlet .
Main family characteristics centrifugal pumps. They are primarily designed as cargo pumps, i.e. for delivery of crude oil, oil derivatives, but can also be used for delivery of fresh and sea water and similar media.

  • Capacity – Q = 1000 – 6000 m3 / h
  • Delivery height – H = 90 – 170 m

PUMP CONSTRUCTION FEATURES

  • axially split casing
  • hydraulically balanced double suction impeller
  • mechanical seal on shaft

 

STANDARD MATERIALS

  • Casing – Nodular cast iron GGG 50, or Ni-Al bronze
  • Impeller – Nickel aluminium bronze, or stainless steel
  • Shaft – Hi grade stainless steel

 

DISTINCTIVE ATTRIBUTES

  • hydraulic characteristics provide very high operating efficiency with excellent suction performanceeasy
  • access to rotating pump parts
  • easily accessible lower bearing
  • possibility of monitoring of all pump operating characteristics (temperature, pressure, vibrations, mechanical seal leakage)

 

PUMP DRIVE

  • marine steam turbine TTK VK
  • frequency controlled marine electric motor
